--- Comment #15 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Eric Gallager from comment #14) > Oh right, if we're considering changing things for plain-C here, too, then > maybe have it enabled by -Wc++-compat there? Or rather, for plain-C modes, where "XY" is 99 or newer: -std=cXY: enabled by -Wc++-compat -std=gnuXY: still completely opt-in; -Wvla must be enabled explicitly (and then for the pre-c99 modes, well, I guess they'd just keep their current behavior)
